摘　　要：冬季温室内自然光照不足，唐菖蒲生长虽正常，但花芽大部分或全部败育。全生育期采用高压钠灯补充１２小时５０００ｌＸ光照，花芽发育较好。唐菖蒲３叶期至开花期对光强很敏感，在此期间补充１２小时５０００ｌＸ的光照，可降低花芽败育率。增施０．７μＬ／Ｌ的ＣＯ２可以促进唐菖蒲的营养生长，使干物质含量增加，鲜花质量提高，但在光照不足时，增施ＣＯ２不能防止花芽败育。In winter, the scarcity of solar irradiance causes a serious flower bud abortion in forcing of Gladiolus in glasshouses; 12h. 5000lx supplementary light by SON-T reduced blasting plants and produced marketable cut-flowers of gladiolus. The stage from the 3rd leaf to anthesis was the most sensitive stage to light intensities. Adding CO2 concentration to 0.7 μL / L accelerated the growth of Gladiolus but was not effective on avoiding flower bud abortion.
